the scales that swell during anthesis and thus promote the flower’s opening; they are found in most grasses.

Two questions that arise when lodicules are considered are 1) the homology of lodicules and 2) the distribution and pattern of diversification of lodicule types.
In Clifford's (1987) interpretation, the occurrence of lodicules in all true florets of the early grasses serves as evidence that most grasses have only subterminal flowers (see the previous section).
The homology of lodicules with other organs in nongrasses is ambiguous.
However, some grasses that lack lodicules also open at anthesis (e.
Although such characteristic grass features as spikelets and lodicules may not have been present in the earliest grasses (see above), the grass-type fruit, with a lateral and well-developed embryo (char.
Three additional characters may be synapomorphies of this group, but can be optimized equally parsimoniously elsewhere: presence of two lodicules (char.
In all five of these genera, the species for which character scores are available have membranous, nonciliate ligules; absence of bicellular microhairs (except possibly Duthiea; see Watson & Dallwitz, 1992); two or three lodicules that are lanceolate, unlobed, and non- or weakly vascularized (including Duthiea, pers.
Morphology of lodicules, their variability and importance in the taxonomy of the Poaceae family.
Character 14 is scored as ambiguous in Streptochaeta and Anomochloa, as the homology of structures sometimes called lodicules in those taxa is ambiguous.
Stipa = [23], three or very rarely two lodicules (Bor, 1968; Tzvelev, 1977).
